  • Degassing and microstructure refinement of shape casting aluminum alloys
    Patent number: 9981310
    Abstract: A degassing and grain refinement system for a cast aluminum-based component and a method of achieving both hydrogen gas presence reduction and grain size reduction in a cast aluminum-based component. Ultrasonic vibrations are imparted to both the liquid metal travel path from its source to the mold to achieve the reduction in hydrogen gas in the molten metal, as well as to one or more locations within the mold to achieve relatively small and equiaxed grains in the component upon solidification.
    Type: Grant
    Filed: September 1, 2015
    Date of Patent: May 29, 2018
    Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLC
    Inventors: Qigui Wang, Devin R. Hess, Jason R. Traub, Christopher D. Cogan, Andrew J. Genualdi
